Textual ETL
Textual ETL can greatly alleviate the challenges facing the organization trying to hear the voice of the customer. The restaurant can actually listen to all of their customers in an accurate and easy to understand manner.
The architectural rendition of how textual ETL works is shown in Fig 7.1.
Textual data in the form of customer comments are fed into textual ETL. You can feed as many as you like into textual ETL. Textual ETL then reads, analyzes, and converts the comments into a database. Once the comments have been converted into a database, they can then be analyzed by a standard analytical program. Then management can see what the customer is saying.
